Teaching application scheme of Ruiguan nano blackboard (double system+simulation laboratory)
1. The integration and evolution of traditional and smart nano-screens.
Retain the traditional advantages: the nano screen continues the chalk writing function, and the surface supports the liquid ink pen writing, which is easy to wipe without leaving marks and meets the traditional teaching habits of teachers; The fuselage is round without sharp edges and corners, and the tempered glass panel is riot-proof and scratch-proof, which is suitable for high-frequency classroom use scenes.
Nano-screen upgrade of intelligent terminal: integrate the functions of projector, curtain, TV, tablet, computer and audio, replace the traditional multimedia equipment, and simplify the classroom layout through integrated design.
2. Nano-screen dual-system collaborative teaching support
System configuration: equipped with Android 6.0/8.0/9.0 system, optional OPS host computer (Intel Core i3 processor, 4G memory, 128GB SSD), one-click switching between Windows and nano-screen Android system.
Nano-screen function division: Android system supports fast start-up teaching tools and wireless screen transmission; Windows system adapts to complex teaching software to meet high-performance requirements such as courseware making and simulation experiments.
3. Teaching value of simulation laboratory
Nano-screen experimental scene restoration: built-in physical and chemical simulation laboratory, through 3D modeling to restore the experimental process, support dangerous experimental simulation (such as chemical reaction, circuit test), and avoid security risks.
Nano-screen interactive operation design: Students can operate virtual experimental equipment by touch, observe experimental phenomena and record data, and analyze experimental principles with the annotation function of electronic whiteboard to improve the efficiency of science teaching.
4. The application practice of nano-screen multi-scene teaching.
Regular classroom: 4K high-definition display (3840×2160 resolution) shows courseware, capacitive touch supports simultaneous writing by many people, and 178 wide angle ensures clear viewing by the whole class; The 8-array microphone picks up 10 meters and cooperates with noise reduction technology to ensure accurate recognition of voice commands.
Nano-screen distance teaching: 1200W camera records classroom pictures, and it is compatible with nailing and other platforms to realize live teaching; The function of wireless screen transmission supports mobile phone and flat screen projection, which is convenient for displaying students' homework or external teaching resources.
Nano-screen extension after class: Courseware can be saved by scanning code, and students can obtain review materials through K12 education cloud platform; Teachers use the teaching data to repeat the teaching process and optimize the teaching plan through the analysis of wrong questions.
5. Highlights of improving the efficiency of nano-screen teaching
Resource integration: integrating massive teaching software and cloud database, covering all subject materials from primary school to high school, supporting intelligent lesson preparation and online updating, and reducing teachers' lesson preparation time.
Convenient operation of nano-screen: the five-finger long press screen is switched to the traditional blackboard mode, and the front USB interface and shortcut keys (eye protection, screen recording, etc.) simplify the operation; Support high-altitude camera access, quickly display paper materials and annotate them.
